Trump signs executive order targeting North Korea's trading partners

"For too long North Korea has evaded sanctions and used the worldwide financial system to facilitate funding for its weapons and mass destruction and ballistic missile programs", he said.

Prime Minister Shinzo Abeaddressed the U.N. General Assembly on Wednesday, calling for strict implementation of U.N. Security Council resolutions against North Korea, which has conducted a series of nuclear tests and missile launches.

The Japanese leader said he and Trump also confirmed in their meeting "the unwavering USA commitment to the defense of Japan and the fact that Japan and the United States are with each other 100 percent", Abe told reporters.

"No bank in any country should be used to facilitate Kim Jong Un's destructive behaviour", Mnuchin told reporters, referring to North Korea's leader.

"Dialogue for the goal of having dialogue is meaningless", Abe said at the New York Stock Exchange. He said that, in the past, other countries have not done what they should to rein in North Korea.

Abe reiterated Wednesday that Japan consistently supports the US stance that "all options are on the table".

Abe said diplomatic attempts to get North Korea to abandon its nuclear aspirations have failed over two decades.

But he said that did not go far enough, as North Korea has "already demonstrated its disregard" of the resolution by firing a ballistic missile over Japan into the Pacific Ocean on September 15, "before the ink on (the resolution) was even dry". "I intend to put forward daring policies unlike any that have come before", said Abe, who was scheduled to address the United Nations General Assembly later on Wednesday.

Abe drew attention to the unresolved issue of North Korea's abduction of Japanese nationals in the 1970s and 1980s, noting that November will mark 40 years since the abduction of 13-year-old Megumi Yokota.

"The prime minister made specific mention [of Megumi]". Our new executive order will cut off sources of revenue that fund North Korea's efforts to develop the deadliest weapons known to humankind.
